This Dushka 12.7mm AAMG is attached to the Andreivian Turk Regional HQ attacking Tuzkhur. It's a Viet Cong team by SHQ (I think) but it'll pass as Andreivian in the heat of battle.
Finally, one of the "Wandering Monsters" in the game is this US Army PsyOps team. All of my modern America figures are a mix of Revell and Esci plastics. The Hummer is a Dragon ready-made.
